A device for determining and displaying at least one physical, chemical or biological property of a test liquid

摘要

A device for determining and displaying at least one physical, chemical or biological property of a test liquid or for detecting substances and/or organisms contained therein by reaction with at least one indicator or reactant. The indicator(s) ( 2.0 ) is/are can be accessed in or via at least one reaction chamber ( 1.5 ) provided with at least one inlet for the test fluid. Said device is embodied in the form of a deep-drawn cup-shaped element ( 1.1 ) which is scaled by a covering film ( 1.2 ). The shape and/or material properties of the reaction chamber(s) is/are preferably selected in such a way that a reset effect is created after deformation such that the original shape can be restored by creating an absorption effect until the original volume is substantially re-created.
